Static target restraining method for ground surveillance radar system

Abstract

The invention discloses a static target restraining method for a ground surveillance radar system. The static target restraining method for the ground surveillance radar system comprises the steps that processed target detection information of the front end of a radar is obtained; interframe accumulation processing is carried out on the target detection information, and a two-dimensional image isformed according to the target detection information after the accumulation; edge extraction is carried out on the two-dimensional image, and target detection information which belongs to a same target after the extraction is obtained; static target area judgment processing is carried out on the target detection information which belongs to the same target, and a static target area range is markedout; and restraining processing is carried out on the target detection information in the static target area range, and target detection information after the static target restraining is obtained. According to the static target restraining method for the ground surveillance radar system, the problem that the ground surveillance radar system cannot accurately mark off the static target area due to variation of detection scenes and erecting sites is solved, the restraining speed of a static target and the detection precision of a moving target are improved, and a reliable data foundation is provided for subsequent track processing.

Description

technical field [0001] The invention relates to the technical field of real-time suppression of stationary targets of a ground surveillance radar system, in particular to a method for suppressing stationary targets of a ground surveillance radar system. Background technique [0002] The ground surveillance radar system is an integrated system of radar and photoelectric imagery, which conducts all-weather surveillance of ground targets and low-altitude targets including drones and helicopters, and the ground surveillance radar system has the ability to classify targets. The speed of the target is combined with the photoelectric and video information to make a comprehensive judgment, identify the target as a single person, multiple people, bicycles, and airplanes, monitor and track the activities of the target, and can grasp and display the position and track of the target. [0003] The stationary target suppression method is to find out the stationary target area according to...
